Kinetic Theory Of Gases Question 88
Question: The specific heat of $ Ar $ at constant volume is $ 0.075k{{g}^{-1}}{{K}^{-1}}. $ Calculate the atomic weight $ ~( R=2calmo{{l}^{-1}}{{K}^{-1}} ) $
Options:
A) 40
B) 40.4
C) 40.2
D) 40.80
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ M=\frac{C _{V}}{S _{V}}=\frac{\frac{3\times 2}{2}}{0.075}=40\
Therefore C _{V}=\frac{3}{2}R $
